WILLIAM A. DAVIS, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR OF ONE- HALF HISRIGHT TO S. T. MOOLELLAND, OF SAME PLACE.

IMPROVEMENTIN FASTENERS FOR THE MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 1 84.036, datedNovember 7, 1876; application filed April 20, 1876.

To all whom it may concern.-

-Be it known that I, WM. A. DAVIS, of the city of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Window-SashLock or Fastener; and I do hereby declare the following to be a full andexact description of the same, reference being had to the annexeddrawing, forming part of this specification, and in which Figure l is arear elevation of the lock. Fig. 2 is a front elevation of the same.Fig. 3 is a vertical section ofthe lock and fastener. Fig. 4 is aperspective view of the fastener detached and Fig. 5 is a perspectiveview of the device complete and in position.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to looks and fasteners for window-sashes and itconsists in the novel construction and combination of a plate, hingedbracket, spring, and catch-plate, as hereinafter more fully describedand definitely claimed.

In the drawing, A A are the sashes of a window. To the upper of these,A, is secured, by screws or otherwise, a metallic plate, B, having onthe under or rear side a recess, in which is secured a spring, a. To theplate B is hinged a bracket, 0, having on one side a button, 0, by whichit may be turned to its proper position, either in a line with, at a ata right angle to, or flat down upon, plate B, in either of whichpositions it is retained by spring a. D is the catch-plate or fasteningdevice. This is secured upon the upper edge of the lower sash A; and itconsists of a flat segmental plate, d, part of the periphery of which iscut down slantingly, so as to form a double step or shoulder, e e. Tothe edge of plate d is secured a spring, f, which may be depressed by abutton, a.

The method of adjusting and operating my improved sash-fastener will bereadily understood from the foregoing description, and by reference tothe drawing hereto annexed. The plate B is secured to the upper sash ofawindow, and to the upper edge of the lower sash is secured thecatch-plate or fastening device D in such a manner that when the bracket(J is in a position shown in Figs. 1 and 2 it shall rest upon step orshoulder c, and thus be prevented from turning by the spring f. Thebracket 0 may have a downward projection, 12, as shown in the drawings,so as, to engage more readily with the fastening device. When it isdesired to open the window, the spring f.

is depressed by means of the button i, and the bracket 0 may then beturned sidewise, so as to admit of the opening of either sash. If it isnot desired to fully open the sash, the bracket 0 may be partiallyturned, and the button 0, by coming in contact with the upper edge ofthe lower sash, will then prevent the window from opening more thanpartiatly.

My improved sash-fastener is simple,'cheap, and easily adjusted andoperated.

Having thus described my invention, 1 claim and desire to secure byLetters Patent of the United States-- 1. The plate B, having spring a,and. hinged bracket 0, arranged to operate substantially as and for thepurpose herein shown and specitied.

2. The improved sash lock and fastener herein described, consisting ofthe plate B, having spring a, and hinged bracket 0, in combination withthe catch-plate or fastening device 1) herein described, all arrangedand operated substantially in the manner and for V the purpose hereinshown and specified.
